fix #66: change wizard registration in TCA

This fixes the following notice in the deprecation.log:

The way registering a wizard in TCA has changed in 6.2. Please set module[name]=module_name instead of using script=path/to/script.php in your TCA. The possibility to register wizards this way will be removed in TYPO3 CMS 7.
